An Experimental Study of Spherical Agglomeration of Benzoic acid And Influence of Process Parameters
Abstract: Through the process of drowning-out crystallisation in three partly miscible solvent mixtures, sphere aggregates of benzoic crystal have been successfully created. The mixture of benzoic acid, isopropyl alcohol, and bridging liquid is supplied to an agitated crystallizer with water acting as the anti-solvent. When a substance crystallises, little crystals are formed, and the bridging liquid causes the crystals to group together. Different solvents are utilised because benzoic acid crystals wettably …

Integration of Photo-catalysis of Ultraviolet Rays for Chlorination Process of Methane Conversion into Mono-, Di-, Tri- and Tetra-Chloromethane
Abstract: Alkanes the most basic of all organic compounds undergo very few reactions due to its stability. One of the reactions is halogenation, or the substitution of single hydrogen on the alkane for a single halogen to form a haloalkanes. Example of this halogenation of alkanes is the chlorination processes. It is well established that methane-chlorine mixture undergoes substitution reaction at the temp of about 400ºC and presence of light without …
